Carbocysteine

Carbocysteine (also known as carbocisteine or S-carboxymethyl-L-cysteine) is a mucolytic agent used in the treatment of chronic obstructive pulmonary disease (COPD) and other conditions characterized by excessive or thickened mucus. It is a derivative of the naturally occurring amino acid cysteine.

Mechanism of Action

Carbocysteine works by breaking down the structure of mucus molecules, making the mucus less viscous and easier to expel from the respiratory tract. This is achieved through the modification of the glycoproteins in the mucus, which reduces its thickness and stickiness.

Medical Uses

Carbocysteine is primarily used to manage conditions where mucus production is a problem, such as:

• Chronic obstructive pulmonary disease (COPD)
• Bronchitis
• Asthma
• Sinusitis
• Otitis media with effusion

Dosage and Administration

Carbocysteine is available in various forms, including oral capsules, syrups, and granules. The dosage and administration depend on the specific condition being treated and the patient's response to the medication. It is important to follow the prescribed dosage instructions provided by a healthcare professional.

Side Effects

Common side effects of carbocysteine may include:

• Gastrointestinal disturbances such as nausea, vomiting, and diarrhea
• Skin rash
• Allergic reactions

Precautions

Patients with a history of peptic ulcer disease should use carbocysteine with caution, as it may exacerbate the condition. It is also important to inform the healthcare provider of any other medications being taken to avoid potential drug interactions.
